Lec 10 MIT 6.451 Principles of Digital Communication II
PROFESSOR: Welcome to class again. This time it's not Professor Forney it's me, so my name is Ralf Koetter. You guys have some substantial chalk here at MIT. And I'm visiting here from the University of Illinois, so Professor Forney thought I could teach this class here. All right, let's see. So I understand that last time, last Wednesday, you went through all the finite field stuff, meaning, so you know what that would mean, the finite field. There's p elements, p to the m elements. Whatever q you have here, is a power of a prime in order to be a field. So this one, as a notation, is a ring of polynomials. You've seen that too. So I assume you know everything about finite fields that you will need to know here, at least, except for one more theorem which Professor Forney told me he did not cover. And this is the fundamental theorem of algebra. I have to write a little bit smaller with this thing here, otherwise I'll run out. AUDIENCE: [UNINTEL...
